To all whom it moy concern: e

Be it known that I, Wrmimn J. OHnmn, a. citizen of theUnited States,residing at Washington, in the District of Columbia, have inventedcertain new and useful Improvements in Submariho Boats; and I do'declarethe following to be a hill, clear, and exact description of theinvention," such as will enable others skilied in the art-to whichitappertains to make and use the earns.

This invention relates to improvements in submarine:

boats.

' The object of the invention is character having arranged therein awater-tight com pertinent; in which is adapted to be placed alife boat,means being provided whereby should the sub-inslrine, boat for anyreason fail to rise after being submerged, .the occupants of the hostmay. enter the life boat and thereby escape from the sunken vessel. 1

With the above and other objects in View, the invsntion consists ofcertain novel featnresoi construction, combination and arrangement ofparts, as will be here:- inaiter described and claimed.

In the accompanying drawingsz-Figure 1 is a side. view of a subdnarineboat, partly in section, showing the application and arrangement of theinvention; 2 is an enlarged cross sectional view through the "life boatcompartment and a portion of the submarine ves sel, showing the lifeboat arranged in said compartment; Fig, 3 is an enlarged dctailsectional view through the trap door or hatch opening into the life boatcompartmentfrorn within the sub-marinev boat; and Fig. i is a. detailview of the brace and its connections for supporting one of the outsidedoors or'hatchos of the life boat compartrnont. i

Referring more particularly to the drawings, 1 dcnotos a sub-marineboat, which may be (if any desired 1 construction; Inthe upper portionof the coat 1, at any.

' throughthe top of the boat 1, said opening being nor mally closed bymeans of hatches or doors 3 and 4 which when shut form a. water-tightclosure for thccompnrtmont 2. The meeting edges of the doors or hatches3; and 4am preferably beveled or ruit-cred, and the'edgc of the hatch 3is provided with a projecting flange 5 which overlaps and rests on theupper side of the hatch 4, as shown. I

, At a suitable point in the compartment is arranged a floating valve 6,said valvebeing here shown and is preferably located in the hatch 4, asshown. The hatch 4 is preferably provided with' one or more supportingbraces 7, said braces being hingedly connected attlieir lower ends in abracket 8 secured to the inner side of the compartment 2, and at itsupper end is adapted to be engaged with a socket casting 9 which isprovided with laterally projecting trunnions 10 adapted to engage asniteble bracket 12 secured to the under side of the to irovldc a host(within hatch 4%, thereby providing a. pivotal connection for the socketcasting 9. The lower end of the brace 7 is provided with laterally grojeing trunnions 13 adapted to engage the bracket 8, thereby pivotollyconnecting the 'the coinpartment 2, as shown at 14. Along the outerupper edges oi-the hatches 3 and 4 sirdformed lateral extensions orflanges 15, said flanges extending over on to the deck or top of theboat 1 some distancetbeyond the edge of the opening of the compertinent2 and are hingedly connected to the top or of the boat at this point,thus forming a prsctically watertight joint at the hinged edge of thedoors.

Supported on a suitable frame or table within the inclooed andwater-tight with the exception of a batch or door-way formed in the-topof the same, which is compartmentQis s. life boat 16, said boat beingentirely adapted to be closed by a suitable trap door or hatch 17aperturcd bloclr 18, through which is passed a locking bolt 19. Thisbolt is adapted to be screwed into a threaded recess 20 formed in theadjacent engaging edge of tlie hatch 3, thereby securely clamping saidhatch into engagement with the top of theblocl: 18 and holding theformer in a water-tight closed position The lock lio lt 19 is providedwith a stop colldr 21, which is adopted to engage the under side oftboofiset portion of the block 18, as shown, and is provided with ahandle by which the same may be readily screwed into en gsgement tviththe threaded recess in the edge of the hatch 3. 5

In the bottom of the compartment 2, preferably near onecnd is formed adoor or hatch-way 22 adapted to be closed. a hinged hatch or door 23,said hatch or door being adapted when shut to form a water-tight closurefor the hatch-way 22. 'The batch 23 is provided on both sides withsuitableiastoning devices by means of which the same may be locked fromwithin the compertinent 2 or from. the body of the vessel. The lockingdevices preferably consist of bolts 24 hingedlyconnected to the innerand outer side oi the hatch 23, and

on which are adapted to be screwed winged nuts 25 On the inner and outersides of the floor of the comthe pressure within said compartment willequalize mit the life boat to rise through the opening to the surface ofthe water.

adjacent surface of the floor of the cornpartment 2, therebyiorming awater-tight closure for the hatch plate 23. The trap door or hatch 17 ofthe life boat is constructed and locked in a similar manner to thatdescribed in connection with the hatch 23 except that the hatch 17 hasits locking device on the inside only.

In the bottom of the compartment 2 at any suitable point is arranged adischarge valve 27, with which is connected a drain pipe 28 leading fromthe bottom of the boat 1, whereby water may be drained from the,tiompartinent 2 when desired. Secured to the upper sides of the hatches3 and 4 adjacent to the meeting edges of the same are rings 29 to whichmay be attached suitable cables for holding the hatches 3 and 4 in anopen position, when desired.

In use, should the sub-marine boat 1 for any reason fail to rise to thesurface, the crew may leave the same by entering the compartment 2through the trap door 01 hatch-way 22 closing the door after them. Afterclosing said hatch-way, the crew will enter the life boat through the.door-way therein. The last man to enter said door-way will first releasethe hatches 3 and 4 by unscrewing the locking bolt 19 and opening theflooding valve 6, after which he enters the life boat and closes andsecurely locks the hatch or trap door 17. The water entering thecompartment2 through the flooding valve will float the life boat in saidcompartment and or over come the pressure of water on the out side ofthe door or hatches 3 and 4, thus causing the same to open by reason oftheir hollow buoyant construction and per- By hinging the hatches. 3 and4 as herein shown and described, the same will swing up and back farenough to permit the life boat to pass freely from the compartment- 2without meeting any obstructions on said doors or hatches. By the use ofa crew of a' sunken sub-marine boat may safely leave the smile From theforegoing description, taken in. connection j with the accompanyingdrawings, the construction and operation of the invention will bereadily under; stood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction maybe resorted to with out departing from the principle orsacrificing any of the advantages of this invention, as defined by therip pended claims.

Having thus described my invention, what l claim as new and desire tosecure by liettcrs-lhitcut, is,
